The Jetson GPIO library provides four ways of numbering the I/O pins. The first two correspond to the modes provided by the RPi.GPIO library, i.e BOARD and BCM which refer to the pin number of the 40 pin GPIO header and the Broadcom SoC GPIO numbers respectively. The remaining two mode...
首先用 'devmem 0x0300xxxx 32 0xxx' 修改引脚的PINMUX到GPIO 寄存器查找方式(以A22为例):在此处下载SG2002寄存器手册,手册中查找XGPIOA[22],在表格中对应到GPIO,shell命令: 'devmem 0x03001050 32 0x03' # xxx 为上图中Linux GPIO NUM,如A22:num=502num=xxxecho${num}>/sys/class/gpio/export# GPIO ...
@rzeldent I isolated the problem to the UI initialization. If I remove it from my code entirely, I no longe have any issues reading/writing/append to files from the SD Card. Bellow you can see a simple evidence of the issue. According to...
I noticed that External Wakeup can be used to wake DeepSleep with RTC GPIO, but I didn't find any description on the web about which pin of the ESP32 C6 can be multiplexed as RTC GPIO. Can you make a suggestion? See thedatasheet, section 2.3.2. Long story short: GPIO0 to GPIO7 ...
Check the current value and configuration for the GPIO of interest (for example GPIO 147): fgrep 147 /sys/kernel/debug/gpio with example output being: gpio-147 (MCP251x CAN INT) in hi irq-274 edge-falling Which indicates GPIO 147 is configure as an input, currently has a high logic ...
So, what exactly in the device tree (or what registers) do I have to write in order to configure this pin as input? So far I have done the following: 1. Set bit 5 of register IOMUXC_GPR_GPR6 (GPR_SAI1_SEL1) to 1 (SAI1_MCLK) in u-boot code 2. Removed the "...

上图是我们电机开发板使用的编码器接口原理图,通过连接器与STM32的GPIO相连,一共4个通道,可以同时接入两个编码器。本实验使用PC6和PC7两个引脚,对应TIM3的CH1和CH2。 4.5.2.软件设计¶ 本编码器测速例程是在减速电机按键控制例程的基础上编写的,这里只讲解跟编码器有关的部分核心代码,有些变量的设置,头文件的...
